PAPER-FOLDER.

SPECIFICATION forming part of Letters Patent No. 512,944, dated January 16, 1894. Application filed March 30, 1893. Serial No. 68,251- (No model) To all whom it mag concern: Be it known thatl, ELIJAH W. CARR, of San Antonio, in the county of Bexar and State of Texas, have invented a new and Improved Paper-Folder, of which the following is a full, clear, and exact description.

My invention relates to improvements in paper folders of the rotary kind. These f0lders, as heretofore constructed, have been very complicated and hence expensive and likely to get out of order, and they have also-been constructed with movable folding knives and cutting blades and have usually been arranged so that the paper being folded has, at certain times, a backward'movement through the machine.

The object of my invention is to produce a rotary paperfolder which is adapted to fold newspapers, as they come from any kind of a press in a continuous web, to produce a machine of this class of the greatest simplicity, to arrange the parts of the apparatus so that paper will be cut into sheets of the correct length, to construct a folding attachment so as to form folds parallel with the columns of printed matter in the paper, and also ,to arrange the cylinders of the machine so that no knives are employed which move in relation to the cylinders; and, further, to arrange the apparatus in such a way that the paper sheets will be fed continuously forward and folded in the simplest possible manner.

To these ends my invention consists of certain features of construction and combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification,

in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a sectional diagrammatic view of the folding cylinders and shows the posi-' tion of the web as it is being cutand the position of the severed sheet as the first fold is being made. Fig. 2 is adiagrammatic 'view of the foldingcylinders and shows the position of the sheet while the first fold is being rolled down and the sheet carried forward to be again folded. Fig. 3 is a similar view and shows the. position of the cylinders while the second fold in the paper is being made. Fig. 4: is a broken detail view, showing the manner in which the folding rollers in the cylinders are revolved; and Fig. 5 is a detail section on the line 5-5 in Fig. 4c.

In carrying out my invention four cylinders, 1, 2, 3 and dare employed, these being arranged in series, as illustrated and as hereinafter described, and it will be understood that the cylinders may be supported and driven in any usual way, and this construction is'therefore not shown in the drawings. The cylinder 1 serves in connection with the cylinder 2 as a cutting cylinder, while the cylinders 2, 3 and 4 serve as folding cylinders.

The web as it comes from the press is fed between the cylinders 1 and 2 in any convenient way, and the cylinder 1 is provided on one side with a fixed knife 5 which registers with a groove 6 in the face of the cylinder 2, so that 76 at each revolution of the cylinders l and 2, the web will be severed; and the size and speed of the cylindersare such that a sheet .of paper cut 06 will correspond to the size of that is, the cuts will be made a newspaper; between each printed paper.

In the face of the roller 2, diametrically opposite the groove 6. ries of parallel folding rollers 7, 7?

on the side is a seand 7 i which turn in a recess 7 in the face of. the So cylinder, but one of these rollers may be dispensed with without affecting the principle of the invention. The rollers are used in making the first fold in the paper and the paper is forced between the rollers 7 and 7 is secure ne 1 e o t e cylinder 3 andprojects from its face. The cylinder 3 is timed so that the blade 8 will strike the paper at the center and partially double it so 0 as to force the doubled-portion 'between the rollers 7 and 7,'after which it passes behind theroller 7 a and over the guide roller 7 b and is engaged by the grippers on the roller 4, as described presently. i 7 provided with a longitudinal-groove 9 with which the blade 8 registers, and this enables the blade to pass the roller 4 without being broken.

' Theg'rippers 10 are held in a recess 10* in ice the face of the roller at and are of the usual kind, and therefore not shown in detail. In the face of the roller 4: are arranged rollers 11, 11 and 11", these being exactly like the The roller 4 is also 5 rollers7, 7 and 7 described above, and they turn in a recess 11 in the face of the cylinder. The rollers 11, 11 and 11 are used in making the second fold, and the paper is partially doubled and pushed between the rollers 11 and 11 by a blade 12 on the cylinder 3, this blade being like the folding blade 8 above described.

The roller 3 turns opposite the roller 2 and consequently this roller is provided with a groove 13 to receive the blade 12 of the roller 3 and permit the blade to turn withoutinjury. On the back side of the lower and last roller 4 is a chute 14 into which the paper is delivered after being twice folded and it is carried forward against an abutment 15, the paper being supported on the usual parallel rods and pushed down between the rods in the customary manner, so that the final fold, at right angles to the folds made by my folder, may be given it in the usual manner.

The rollers 7, 7 and 7 and the rollers 11, 11 and 11 are turned so as to give a continuous forward movement to the paper and they may be turned in any suitable way,but are preferably turned by the gear mechanism illustrated in Figs. 4: and 5. Here oneof the roller shafts connects by means of a pinion 17 with a fixed gear 18' which is held in a stationary position by. supports 19, and the several roller shafts are connected together by gears 17 Consequentlyas the cylinder2 or 4, as the case may be, revolves, the pinion 17 travels around on the periphery of the gear 18, and movement is thus imparted to the several rollers.

Any suitable guiding mechanism can be employed for leading the paper web between the several cylinders, and I lay no claim to any mechanism of this kind, but a simple form of guiding mechanism is illustrated in Fig. 1. Here the roller 17, which is a common friction roller, turns close to the lower portion of the cylinder 2, so that the paper web 16 will be fed forward between the said roller and cylinder. Above the cylinder 2 are arranged curved finger rods 18, which prevent the paper from rising from the roller; and beneath the cylinders 2 and 3, and immediately above the cylinder fl, is a spring guide 19, one arm of which presses the paper web against the cylinder 3. Beneath the cylinder 3 is arranged aguide 20, which may be composed of a series of fingers or of a single sheet, and it will be seen that the several guiding devices hold the web snugly against the faces of the cylinders. As above remarked, however, any guiding mechanism suitable for the purpose may be used to direct the course of the web.

The course of the web through the machine is as followsz-The web 16 enters betweenthe rollers 1 and 2, and when it has traversed the distance corresponding to the length of a newspaper, the knife 5 registers with the groove 6 and cuts oi the web. The severed paper is guided between the rollers 2 and 3 and the bladeS strikes the severed sheet in the center and pushes its middle portion between the rollers 7 and 7 which flatten the once folded is made to lie over the rollers 11,

ll" and 11 and is pushed between the rollers 11 and 11 by the folding blade 12 audit passes behind the roller 11 and over the face of the guide roller 11" into the chute 14, where it is taken care of in the manner alreadyto specified.

Having thus described my inventlon, I

claim as new and desire to secure by Letters Patent- 1. A paper folder, comprising "a series of three revolnble cylinders arranged to turnin parallel positions and with their faces ad acent to each other, parallel revolnble folding rollers held to turn in recesses in two of the cylinders, folding blades carried by the third cylinder and adapted to project between the rollers of the other two cylinders, and a cutting cylinder arranged in advance of the first folding cylinder and having a pro ecting blade to enter a groove in the said cylinder,

substantially as described.

2. A paper folder, comprising three revoluble parallel folding cylinders arranged in a substantially triangular position, revolnble rollers held in the faces of two of the cylin- 10o ders, projecting folding blades arranged on the second cylinder of the series and adapted to enter between the rollers of the other two I cylinders, and grippers arranged on the third cylinder of the series and adapted to engage I05 and carry forward a paper delivered from the first two rollers, substantially as described.

3. In a paper folder, the combination of a folding cylinder having a recessed face, revoluble rollers held to turn in the said recess H andarranged to lie within the face of the cylinder, the inner wall of the recess lying close to the inner faces of the rollers and serving as guides forthe paper web, the rollers being adapted to feed a web of paper between them, I 5

and a second folding cylinder having a folding blade adapted to project between the folding rollers, substantially as described.
